A study on the structure and corrosion characteristics of polyethylene terephtalate and polyvinylchloride

The corrosion rate of polymer polyethylene terephtalate and polyvinylchloride was characterized at various condition by potentiostate / galvanostate method. The cell and working electrode used for this study was specially preparatain, The potential was scanned at foward scan -2V to 3V and reward scan 3V to -2V, at 50mv/s (R: auto - compensation).
